摘要： A method for processing CT colonography input image voxel data representative of 3-dimensional images of a colon having gas and stool tagged with stool tagging agent, to remove the stool from the images. The input image voxel data is generated by an imaging instrument having a characteristic point spread function representative of instrument blurring. The point spread function of the instrument can be empirically determined, and the image data processed as a function of the point spread function to accurately identify and remove the tagged stool. In one embodiment of the invention, portions of the image data representative of the tagged stool and colon tissue are dilated as a function of the point spread function. In another embodiment, portions of the image data representative of the tagged stool are convolved with the point spread function to determine the fractional amount of stool present in the image portions, and the tagged stool subtracted by reducing the intensities of the associated portions of the image by an amount proportional to the fractional amount of stool present.
摘要翻译：一种用于处理CT结肠造影输入图像体素数据的方法，其代表具有标记有粪便标记剂的气体和粪便的结肠的3维图像，以从图像中去除粪便。输入图像体素数据由具有代表仪器模糊的特征点扩散函数的成像仪生成。仪器的点扩散函数可以根据经验确定，并且图像数据作为点扩散函数的函数进行处理，以准确识别和移除标记的粪便。在本发明的一个实施例中，代表标记的粪便和结肠组织的图像数据的部分作为点扩散函数的函数被扩张。在另一个实施例中，代表标记的凳子的图像数据的部分与点扩散函数进行卷积，以确定图像部分中存在的粪便的分数，并且通过降低图像的相关部分的强度来减去标记的粪便通过与存在的粪便的分数量成比例的量。

摘要： A method for processing and displaying colonography image data. First distance tissue pixels representative of tissue within a first distance of gas pixels representative of gas are processed with a first window/level setting to generate a first setting set of image pixels. Second distance tissue pixels representative of tissue within a second distance of the gas pixels are processed with a second window/level setting to generate a second setting set of image pixels. The second distance is a distance greater than the first distance. A colonography image including both the first and second setting sets of image pixels is then displayed.

摘要： An improved method for processing image voxel data representative of 3-dimensional images of a colon to remove the effects of tagged stool. The method uses parabolic curve intensity-gradient models at a transition between two material types as a function of the fraction of the two materials for each of a plurality of two-material type classes, including a gas-tissue transition model, a gas-stool transition model and a stool-tissue transition model. The voxels are classified into one of a plurality of substance classes including tagged stool, gas, tissue and unknown classes. The unknown class voxels are processed to classify the unknown class voxels into one of the two-material type classes. The two-material type class voxels are processed to determine the fractions of materials in each voxel. The intensity of the two-material type class voxels is then adjusted as a function of the fraction of the materials in the voxels.
